In the end we went for Hamilton HJ322 with a Caterpillar 3126 should be a nice commercial set up
. Had a look at your web you build some nice boats, i can see why you go for the foam its not what you call summer time in the pics rrrrrrrrrrr .
The rib that we are going to build is more for the tourist and fishing side of things, have you found a good way of keeping the noise level down? Have you come across any good fresh water fish holding that could be adapted to a rib?
